DEVICE FOR REGULATING THE TEMPERATURE OF AIR SUPPLIED TOJCARBURETERS.

App1ication filed May 8, 1913. Serial No. 766,393.

To all whom it may concern:

Be it known that I, WILLIAM M. SIMMoNs, of Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Devices for Regulating the Temperature of Air Supplied to Carbureters; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in device for regulating the temperature of air supplied to the carburetor of a gasolene engine, the object being to provide means whereby the air may be heated before passing to the carburetor, or may be drawn from.

the outside into the carburetor without any pro-heating and it consists in the parts and combination of parts as will be more fully explained and pointed out in the claims.

In the accompanying drawing, Figure 1 is a diagrann'natic view showing my appa ratus applied to acarburetor; Fig. 2 is a view in elevation of the air chamber the wall of the latter being partly broken away,

and Figs. 3 and d are views in section of the same.

1 represents acarbureter which may be of any approved COIlStlllCtlOll. In the form shown, the gasolene is discharged into the carburetor from pipe 2 while the combined air and vapor pass through the end 3 by suitable pipe connection into the cylinder or cylinders (not shown).-

4 is an air pipe leading into the carbureter and provided with an intake valve 5 yieldingly held againstits seat 6 by a spring 7, and which may be moved downwardly from its seat, by suction of the engine cylinder, or by positive impulse applied by any suitable mechanism. Located over the intake valve 5 and preferably secured to the seat of said valve, is the air chamber 8, cylindrical in form and of slightly greater diameter than the valve 5. This chamber is open at its bottom, and is connected with a pipe 9 leading from a drum or jacket 10 through which the exhaust pipe 11 from the engine passes, so that the air within. the jacket 10 will be heated by its intimate contact with the hot exhaust pipe 11. The drum or jacket 10 is provided with the perforations 12 through which the air enters the jacket, and the latter'is, as previously explained, in direct communication with the 9, so that all air enterin jacket or drum 10 may be directed into the air chamber 8. This chamber 8 is provided in its side wall, preferably diametrically opposite the discharge end of pipe 9, with an opening 13, preferably of greater size than the discharge end of pipe 9, which opening may be wholly or partly closed by the gate 14. This gate is curved to conform to the curvature of the wall of chamber 8, and is preferably suspended from the top of chamber 8 by the pivot pin 15, the latter passing through the flange 16 which projects from the sliding gate at the top of the latter. The gate is mounted to slide within the air chamber and is pivoted at the axis of the latter, so that as the gate is turned to open the air inlet 13, it moves inside of the chamber and approximately concentric with the in nor surface of the side Wall of the-latter. The gate 14 is provided. with a handle 17 by which it may be turned. The openings and gate in the air chamber 8, are so located and proportioned that the gate 14L may be moved to partly open position without interfering with the free discharge of hot air into the chamber, thus permitting the air entering the chamber 8 through the outer air opening to mix with the hot air before entering the carburetor. By opening the gate still farther, the hot air discharge opening into said chamber will be partly closed, and by moving the gate to wholly open position the hot air discharge will be wholly closed, thus shutting off entirely the supply of hot air, and supplying the carburetor with air at normal temperature.

In cold weather it is diilicult and at times impossible. to get the power out of an autogine for a considerable time. If the machine is used before the engine gets thoroughly hot, the mixture of gasolene must be much richer than is ordinarily required, and the engine run at a higher speed in order to get satisfactory results.- lVith this device the air may be heated to a high degree so that at the instant it combines with the va por of gasolene, the mixture will be at a temperature suflicient to permit the engine preliminary heating up. In more moderate temperatures, the gatemay be partly opened air chamber 8 through the pipe connection mobile motor without first running the ento be run at once at high speed without any I latter.

It is evident that many slight changes might be resorted to int he relative arrangementof parts shown anddescribed Without departing from the spirit and scope .of my invention. Hence I would have it understood that I do not Wish to confine myself to the exact construction and arrangement of parts shown and described, but

Having fully described my invention What I I claim as new and desire to secure by Letv ters-Patent, 1s:

1. A device for regulating the temperature of air supplied to the carbureter of a gasolene motor, consisting of an air chamber having an inlet for cold air and an inlet for hot air, a single gate adapted to be adjusted to admit cold air Without restricting the hot air inlet and also adapted to be turned to wholly close one inlet and open the other, an air outlet adapted to lead to the carbureter and a valve for closing said outlet.

2. A device for regulating the temperature of air supplied to the carbureter of a gasolene motor, consisting of a chamber to the carbureter, a single gate adapted to,

be adjusted to admit cold air Without 1e stricting the hot air inlet and also adapt-ed to be turned to wholly close one inlet and open the other and a spring actuated valve normally closing the outlet from said chamber.

3. A devicefor regulating the temperature of air supplied to the carbureter of a gasolene motor consisting of an air chamber having a cold air opening therein, a hot air inlet openin therein, and a hot air pipe for discharging liot air through saidhot air inlet opening into said chamber, a single sliding gate adapted to be adjusted to admit cold air Without decreasing the size of the hot air inlet opening, and also adapted to be adjusted to Wholly close one inlet and open the other, a pipe connection from said chamber'adapted to lead to a carbureter and an automatic valve in said pipe for controlling the passage of air from said chamber.

In testimony whereof, I have signed this specification in the presence of two subscribing Witnesses. v p
